Which sound apps do you use with MG?

I’m looking for more apps to use with MG. I plan on trying it in live performance. Right now I use Korg Gadget, which a great app but the setup is not ideal for playing live.
I like AudioKit Synth One but it crashes over and over. At least Gadget is rock solid, it never crashes or freezes.
Seems like a lot of synths are $5-10 and I want to ask what others are using before randomly buying them.

For synth pad sounds in AUV3 Format- give Klevgränd “Pad - Lush Pad Synthesizer” a chance.
(connect Midi via Audiobus from MG to the Synth - very solid as far as I can tell)

I am running GarageBand using Virtual Midi. Great sounds. Also Digital D1 (auv3) and Primer - Audible Genius - Free . If you have a Yamaha MX keyboard like MX61 etc, then Yamaha’s FM Essentials is a good auv3 synth as well.
